If there is a failure during kstrtobool_from_user()
rtw89_debug_priv_btc_manual_set should return negative error code
instead of returning the count driectly.

Fix this bug with the following changes:
- Return an error code instead of a count after a failed call 
of the function "kstrtobool_from_user".
- Omit the label "out" with this source code correction.

Fixes: e3ec7017f6a2 ("rtw89: add Realtek 802.11ax driver")

Changes in v2:
- Corrected the format of this patch
- Used variable ret instead of goto out
Changes in v3:
- Improved change description
